Just had a thought. Suppose we take Sedanmans neat Double Port Dolmar muffler and put it on a Strato Charged double port carb?
Outta kick some grA$$ & chips!
Lower port directly in line with the cylinder intake port as normal. Air is drawn in just like normal engine, because that part is just like regular engines.
Upper port lets air in thru the manifold to tubes that run to the outside of the cylinder at the transfer ports.
Transfer ports are inside, but holes are cast-machined at the top of the transfer port. This is not the cheaper 'window porting' we're seeing by some companies today.
Think of it like a transfer port that has a specail hole in it at the top.
Now, think of how a piston which acts as a sliding valve opens & closes the transfer port.
As the piston is coming upward with a fresh intake charge, air now comes thru the upper carb port, thru the tubes on the outside of the cylinder, thru a small Reed valve at the top of the transfer port.
Air under simple normal atmospheric pressure (no parts) pushes it's way in above the incomming intake charge, and in between the already burning(partly) fuel up in the cylinder head, and moves back towards the exhaust.
It induces clean air, reduces the amount of the escaping burning-unburnt exhaust.
Not only has it limited the unburnt gas, but provides a clean air barrier between the charges.
Acelerated 'swept scavenging' is one way of partly describing a part of it's function.
Pictures will follow tonight or tomorrow
Dan Henry has a top handle saw he's been foolin' with for a long time, and he's been braggin about a Red Max G5000 that hits over 17K.
Was asking about a new compressor, so maybe he's got his own ideas of Strato Charging.
